Rawr I finally managed to beat it, but it took a while :P Good job on the AI!

Thanks - the AI is strong in some situations and weak in others (there are many ways you can trick it into losing), but I'll try to improve on it.

I have to create a connect four game for my CS lab, any pointers you have on how to do it would be nice, I'm having trouble figuring out where to start.

Hey spaceblue! I love the game! Any way I could get the code so I can see how it works and try to improve it with you?

Nice AI! I managed to beat in on my 4th try, got kinda lucky really because I didn't exactly plan it, but it got to the point where the only move the AI had gave me a victory.
